Description

SYSTEME DE CAPTURE D ' ANIMAUX MARINS VIVANTS SYSTEM FOR CAPTURING LIVE MARINE ANIMALS
La présente invention concerne un système de capture d'animaux marins vivants pour chalut de fond ou pélagique. Cette invention trouve plus particulièrement une application dans le milieu de la recherche (pour le marquage des poissons, par exemple) et de 1 ' aquariophilie .The present invention relates to a system for capturing live marine animals for bottom or pelagic trawls. This invention finds more particularly an application in the research environment (for marking fish, for example) and aquarium keeping.
Différentes techniques de capture d'animaux marins vivants existent à ce jour, dont l'une des plus simples consiste à attraper les poissons "à la main" ou avec une epuisette. Une autre technique connue consiste à capturer les poissons avec des nasses ou avec des hameçons montés sur une ligne. Ces techniques ne sont pas très satisfaisantes car les poissons capturés sont souvent blessés lors de leur capture (écailles arrachées, nageoires endommagées, blessures diverses,...), ce qui réduit fortement leur taux de survie. Par ailleurs, ces techniques ne sont pas adaptées à la capture en masse .Various techniques for capturing living marine animals exist to date, one of the simplest of which is to catch the fish "by hand" or with a landing net. Another known technique consists in catching fish with traps or with hooks mounted on a line. These techniques are not very satisfactory because the captured fish are often injured during their capture (torn scales, damaged fins, various injuries, ...), which greatly reduces their survival rate. Furthermore, these techniques are not suitable for mass capture.
L'utilisation d'un chalut permettrait de réaliser une capture en masse, mais ce mode de capture présente à ce jour les mêmes inconvénients que ceux précités quant à la survie des animaux capturés. Aussi, le but de l'invention est de proposer un système permettant la capture en masse d'animaux marins vivants et répondant aux critères suivants:The use of a trawl would allow mass capture, but this method of capture has to date the same drawbacks as those mentioned above with regard to the survival of the animals captured. Also, the object of the invention is to propose a system allowing the mass capture of living marine animals and meeting the following criteria:
- s'adapter à tous types de chalut; - garantir aux animaux capturés dans le système des conditions de survie optimales;- adapt to all types of trawl; - guarantee animals caught in the system optimal survival conditions;
- maintenir les animaux capturés dans un volume d'eau suffisant tout au long des opérations de capture, de remontée et de récupération du système sur le pont du bateau;- keep the animals captured in a sufficient volume of water throughout the capture, ascent and recovery of the system on the deck of the boat;
- supprimer, lors des opérations ci-dessus mentionnées, toute compression et tout frottement sur les animaux capturés ;- remove, during the operations mentioned above, any compression and any friction on the captured animals;
- permettre la capture d'espèces cibles d'animaux; - réaliser un système simple d'utilisation et d'un faible coût de fabrication.- allow the capture of target animal species; - achieve a simple system of use and a low manufacturing cost.
L'invention a pour objet la capture d'animaux marins vivants (poissons, crustacés, céphalopodes, etc..) par un système destiné à former la poche d'un chalut, caractérisé en ce que la poche comporte une partie terminale imperméable formant piscine, munie d'une armature destinée à maintenir la section transversale de la piscine sensiblement constante en forme et en dimension, de manière à garder les animaux capturés dans un volume d'eau suffisant lors de la remontée du système sur le pont du bateau.The subject of the invention is the capture of living marine animals (fish, crustaceans, cephalopods, etc.) by a system intended to form the pocket of a trawl, characterized in that the pocket comprises an impermeable end portion forming a swimming pool , provided with a frame intended to keep the cross section of the swimming pool substantially constant in shape and size, so as to keep the animals captured in a sufficient volume of water during the ascent of the system on the deck of the boat.
Selon un mode de réalisation préféré, la piscine est de forme cylindrique et l'armature est formée par au moins deux cerceaux de forme circulaire ou non, entourant au moins la partie haute et la partie basse de la piscine, la paroi cylindrique de la piscine étant attachée le long desdits cerceaux. La paroi cylindrique de la piscine est, par exemple, attachée point par point, à intervalles réguliers ou irréguliers, le long desdits cerceaux.According to a preferred embodiment, the swimming pool is of cylindrical shape and the frame is formed by at least two hoops of circular shape or not, surrounding at minus the upper part and the lower part of the pool, the cylindrical wall of the pool being attached along said hoops. The cylindrical wall of the swimming pool is, for example, attached point by point, at regular or irregular intervals, along said hoops.
Pour retirer les poissons vivants de la piscine après remontée du système, il est prévu en outre, en amont de la piscine, un premier dispositif d' ouverture/fermeture de la poche .To remove live fish from the pool after the system has been raised, there is also provided, upstream of the pool, a first device for opening / closing the pocket.
Par ailleurs, pour éviter que des espèces indésirables de poissons ne viennent se mélanger, lors de la remontée du système, aux espèces déjà présentes dans la piscine, on prévoit avantageusement, en amont du premier dispositif d' ouverture/fermeture de la poche, un moyen de fermeture de la partie terminale de la poche par restriction radiale. Ce moyen est actionné juste avant la remontée du système.Furthermore, to prevent undesirable species of fish from mixing, during the ascent of the system, with the species already present in the pool, provision is advantageously made, upstream of the first device for opening / closing the pocket, a means for closing the terminal part of the pocket by radial restriction. This means is activated just before the system is raised.
D'autre part, pour retirer les poissons indésirables capturés lors de la remontée du système de capture et bloqués en amont dudit moyen de fermeture de la partie terminale de la poche, on prévoit également avantageusement, en amont dudit moyen de fermeture de la partie terminale de la poche, un deuxième dispositif d' ouverture/fermeture de la poche.On the other hand, to remove unwanted fish caught during the ascent of the catching system and blocked upstream of said means for closing the terminal part of the pocket, provision is also advantageously made, upstream of said means for closing the terminal part. of the pocket, a second device for opening / closing the pocket.
Les caractéristiques et avantages de 1 ' invention mentionnés ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description détaillée qui suit et qui est faite en référence aux dessins joints, parmi lesquels : la Fig.l est une vue schématique d'ensemble du système de capture d'animaux vivants selon l'invention;The features and advantages of the invention mentioned above, as well as others, will become apparent more clearly on reading the detailed description which follows and which is made with reference to the accompanying drawings, among which: FIG. 1 is a schematic overview of the system for capturing live animals according to the invention;
- la Fig.2 est une vue agrandie de la partie terminale de la poche délimitée par le cercle en traits pointillés sur la Fig.l; et- Fig.2 is an enlarged view of the terminal part of the pocket delimited by the circle in dotted lines in Fig.l; and
- la Fig.3 est une vue schématique d'une liaison entre l'armature et la piscine.- Fig.3 is a schematic view of a connection between the frame and the pool.
Un système de capture d'animaux marins vivants conforme à 1 ' invention est représenté schématiquement à la figure 1. Il est destiné à former la poche 1 d'un chalut .A system for capturing live marine animals according to the invention is shown diagrammatically in FIG. 1. It is intended to form the pocket 1 of a trawl.
En référence à la figure 1, la poche 1 est constituée d'une partie avant la, appelée tube, dans laquelle sont canalisés les animaux et d'une partie arrière lb, appelée fond, où ils sont piégés.With reference to FIG. 1, the pocket 1 consists of a front part 1a, called a tube, into which the animals are channeled, and a rear part 1b, called the bottom, where they are trapped.
Selon l'invention, la partie terminale du fond lb comporte une piscine 2 circulaire dotée d'une armature destinée à maintenir la section transversale de la piscine sensiblement constante en forme et en dimension. La piscine 2 est réalisée en toile PVC imperméable. Elle a pour fonction de maintenir un volume d'eau au fond de la poche du chalut après que celui-ci a été remonté sur le pont du bateau, et cela afin de maintenir en vie les animaux capturés. L'armature a, quant à elle, pour rôle d'empêcher toute déformation de la section de la piscine, notamment pour éviter que les animaux capturés soient plaqués contre la paroi de la piscine lors de la remontée du système.According to the invention, the end portion of the bottom 1b comprises a circular swimming pool 2 provided with a frame intended to keep the cross section of the swimming pool substantially constant in shape and in size. Pool 2 is made of waterproof PVC canvas. Its function is to maintain a volume of water at the bottom of the trawl pocket after it has been brought up to the deck of the boat, and this in order to keep the captured animals alive. The role of the reinforcement is to prevent any deformation of the pool section, in particular to prevent captured animals from being pressed against the pool wall when the system is raised.
En référence aux figures 1 et 2, l'armature de la piscine est constituée par deux cerceaux 3a et 3b disposés respectivement autour de la partie haute et de la partie basse de la piscine 2. Des anneaux 6 sont montés sur chacun des cerceaux. Pour rattacher l'armature à la piscine 2, cette dernière est équipée, dans sa partie haute et dans sa partie basse, de deux collerettes externes 4a et 4b auxquelles sont rattachés les cerceaux 3a et 3b.With reference to FIGS. 1 and 2, the frame of the swimming pool is constituted by two hoops 3a and 3b disposed respectively around the upper part and the lower part of the swimming pool 2. Rings 6 are mounted on each of the hoops. To attach the frame to the pool 2, the latter is equipped, in its upper part and in its lower part, with two external flanges 4a and 4b to which the hoops 3a and 3b are attached.
Dans l'exemple de réalisation des figures 1 et 2 , la paroi cylindrique et le fond de la piscine 2 sont soudés ou cousus de manière à former extérieurement la collerette 4b. De même, la paroi cylindrique de la piscine 2 est constituée de deux bandes de toile PVC, 2a et 2b, soudées ou cousues l'une au-dessus de l'autre, le bord inférieur de l'une débordant légèrement sur le bord supérieur de 1 ' autre de manière à former extérieurement la collerette 4a.In the embodiment of Figures 1 and 2, the cylindrical wall and the bottom of the pool 2 are welded or sewn so as to form the outside collar 4b. Likewise, the cylindrical wall of the swimming pool 2 consists of two strips of PVC fabric, 2a and 2b, welded or sewn one above the other, the lower edge of one projecting slightly over the upper edge. on the other so as to externally form the collar 4a.
Des cosses 5 sont ménagés à intervalles réguliers dans les collerettes 4a et 4b. Une corde périphérique 7 est passée dans chacune des cosses 5 pour former une boucle autour de chacun des anneaux 6 et rattacher ainsi la piscine 2 aux cerceaux 3a et 3b. La liaison entre les anneaux 6 et la piscine 2 est montrée en détail à la figure 3. Par ailleurs, dans l'exemple de réalisation des figures 1 et 2 , le fond lb du chalut comporte, en plus de la piscine 2, une bande de toile PVC, 8, cylindrique rattachée à un cerceau 3c pour réduire les efforts exercés par la piscine sur les cerceaux 3a et 3b. Cette bande est disposée en amont de la piscine 2 et est cousue sur une bande cylindrique du filet de fond lb. De même que pour les collerettes 4a et 4b, la bande de toile PVC 8 est munie de cosses dans lesquelles est passée une corde pour former une boucle autour d'anneaux du cerceau 3c et attacher la bande 8 au cerceau 3c.Lugs 5 are formed at regular intervals in the flanges 4a and 4b. A peripheral cord 7 is passed through each of the lugs 5 to form a loop around each of the rings 6 and thus attach the pool 2 to the hoops 3a and 3b. The connection between the rings 6 and the swimming pool 2 is shown in detail in FIG. 3. Furthermore, in the embodiment of Figures 1 and 2, the bottom lb of the trawl comprises, in addition to the pool 2, a strip of PVC fabric, 8, cylindrical attached to a hoop 3c to reduce the forces exerted by the swimming pool on hoops 3a and 3b. This strip is arranged upstream of the pool 2 and is sewn onto a cylindrical strip of the bottom net 1b. As for the flanges 4a and 4b, the PVC web strip 8 is provided with lugs through which a cord has passed to form a loop around the rings of the hoop 3c and attach the strip 8 to the hoop 3c.
Un dispositif d' ouverture/fermeture 9 de la poche, de type fermeture éclair™, est prévu en amont de la bande 8 pour extraire de la piscine les animaux cibles, après remontée du chalut sur le pont du bateau. Ce dispositif est monté sur la face inférieure du chalut, c'est-à- dire sur la face en regard du fond de la mer, dans le sens longitudinal .An opening / closing device 9 of the pocket, of the zipper ™ type, is provided upstream of the strip 8 to extract the target animals from the pool, after the trawl is raised on the deck of the boat. This device is mounted on the underside of the trawl, that is to say on the face facing the sea bottom, in the longitudinal direction.
La fermeture éclair™ 9 est maintenue fermée pendant les opérations de mise à l'eau du système, de capture des animaux au fond de l'eau et de remontée du système. Elle est ouverte lorsque la piscine est posée sur le pont du bateau pour récupérer les animaux marins vivants . A noter que lorsque la piscine est posée sur le pont du bateau, elle est maintenue verticalement en tension par l'enrouleur du chalut pour éviter qu'elle ne s'affaisse et ne laisse échapper l'eau qu'elle contient .The zipper ™ 9 is kept closed during the operations of launching the system, capturing animals at the bottom of the water and raising the system. It is open when the swimming pool is placed on the deck of the boat to recover living marine animals. Note that when the pool is placed on the deck of the boat, it is kept vertically in tension by the trawl reel to prevent it does not collapse and does not allow the water it contains to escape.
Avantageusement, le système de capture est équipé d'un moyen 10 de fermeture de la partie terminale de la poche. Ce moyen de fermeture est destiné à fermer le passage entre le tube la et le fond lb lors de la remontée du système de capture pour optimiser la qualité de la prise et éviter que des espèces indésirables d'animaux ne viennent se mélanger aux espèces cibles déjà présentes et les abîmer. Ce moyen de fermeture est également destiné à éviter une surcharge en animaux du fond lb du chalut .Advantageously, the capture system is equipped with means 10 for closing the terminal part of the pocket. This closure means is intended to close the passage between the tube 1a and the bottom 1b during the ascent of the capture system to optimize the quality of the catch and prevent undesirable species of animals from coming to mix with the target species already present and spoil them. This closure means is also intended to avoid an overload of animals from the bottom lb of the trawl.
Le moyen 10 est installé sur la face supérieure du système de capture au niveau de la transition entre le tube la et le fond lb. Il présente une flottabilité positive pour ne pas écraser la poche et entraver le passage des animaux du tube la vers le fond lb.The means 10 is installed on the upper face of the capture system at the transition between the tube la and the bottom lb. It has positive buoyancy so as not to crush the pocket and hinder the passage of animals from the tube 1a to the bottom 1b.
Ce moyen de fermeture est, par exemple, constitué d'un récepteur acoustique chargé d'actionner un moteur larguant un parachute relié à une corde 11 coulissant dans des anneaux 12 montés sur la périphérie de la poche au niveau de la transition tube/fond. Ce moyen est actionné juste avant la remontée du système de capture. Un émetteur à bord du bateau envoie un signal acoustique au récepteur acoustique du moyen de fermeture 10. En réponse à ce signal, le moteur largue le parachute qui, en raison du déplacement du système de capture, tire sur la corde 11 jusqu'à fermer complètement le passage entre le tube la et le fond lb. Un taquet-coinceur maintient alors le moyen 10 en position fermée.This closure means, for example, consists of an acoustic receiver responsible for actuating a motor dropping a parachute connected to a rope 11 sliding in rings 12 mounted on the periphery of the pocket at the tube / bottom transition. This means is activated just before the capture system is raised. A transmitter on board the boat sends an acoustic signal to the acoustic receiver of the closure means 10. In response to this signal, the engine releases the parachute which, due to the movement of the capture system, pulls on the rope 11 until it closes completely the passage between the tube la and the bottom lb. A cleat-cleat then maintains the means 10 in the closed position.
Avantageusement, en amont de la transition tube/fond, on prévoit un deuxième dispositif d' ouverture/fermeture de la poche 13, également de type fermeture éclair™, pour retirer les animaux indésirables capturés lors de la remontée du système de capture et bloqués au niveau de la transition tube/fond par le système de fermeture 10.Advantageously, upstream of the tube / bottom transition, there is a second device for opening / closing the bag 13, also of the zipper ™ type, for removing the unwanted animals captured during the ascent of the capture system and blocked in the level of the tube / bottom transition by the closure system 10.
La capture d'animaux marins vivants avec un tel système peut être opérée de la manière suivante : - mise à l'eau du système de capture, les fermetures éclair™ 9 et 13 étant fermées et le passage entre le tube la et le fond lb étant ouvert;The capture of living marine animals with such a system can be carried out as follows: - launching of the capture system, the zippers ™ 9 and 13 being closed and the passage between the tube la and the bottom lb being open;
- capture des animaux cibles vivants au fond de l'eau;- capture of target animals living at the bottom of the water;
- fermeture du passage entre le tube la et le fond lb; - remontée du système de capture à bord du bateau; ouverture de la fermeture éclair 13 pour extraire les poissons bloqués dans le tube la par le système de fermeture 10; pose de la piscine sur le pont du bateau, celle-ci étant maintenue verticalement en tension pour maintenir le volume d'eau à l'intérieur; ouverture de la fermeture éclair 9 pour extraire les animaux cibles de la piscine.- Closing the passage between the tube la and the bottom lb; - recovery of the capture system on board the boat; opening of the zipper 13 to extract the fish blocked in the tube la by the closure system 10; placing the pool on the deck of the boat, the latter being kept vertically tensioned to maintain the volume of water inside; opening of the zipper 9 to extract the target animals from the pool.
Ensuite, l'extraction des animaux de la piscine est, par exemple, opérée à l'aide d'épuisettes à filet sans nœuds pour ne pas endommager les animaux. Ces derniers sont ensuite posés sur des brancards pour leur transport vers des cuves de stabulation, en vue de leur marquage . Then, the extraction of animals from the pool is, for example, carried out using net nets without knots so as not to damage animals. The latter are then placed on stretchers for their transport to lairage tanks, for their marking.
